ESCUTCHEON-PLATE.

To all whom it may concern:

Be it known that I, HENRY S. LOGKWOOD, a citizen of the United States,residing at South Norwalk, county of F airfield, State of Connecticut,have invented an Improvement in llscutcheon-Plates, of which thefollowing is a specification.

This invention relates to what are known as escutcheon plates of thetype which are usually made of quite thin sheet metal which is struck upby means of dies so as to make its central portion stand out from thesurface of the door to which it is applied, the back of the plate beinghollow.

These escutcheon plates usually also carry what is known as theknob-rose. Since the two knobs on opposite sides of the door are securedto a shank member which passes through, the pushing or pulling of theknobs bring more or less strain upon the metal of the escutcheon platewhich would tend to buckle the plate because of its thinness unless somefurther support is afforded behind the escutcheon plate. It is not newto provide supporting means for this purpose but so far as 1 am aware ithas never been proposed to support other portions of the escutcheonplate at some distance from the rose.

The objectv of this invention is to provide a support which will notonly resist pressure exerted at the rose, but which will also supportthe plate adjacent to the upper c ttaching screws, the support in thepresent embodiment of the invention being a single combination devicewhich at one end supports the rose center against pressure in thedirection toward the wood surface behind it and at the other end takesup the pressure of the upper screws so that the latter cannot be causedto force the edge of the escutcheon plate into the wood.

Another object of the invention is to provide a connection between therose center or thimble and the support so that neither can turn or workloose so as to rattle.

To these ends the invention consists in the construction and combinationof parts substantially as hereinafter described and claimed.

Of the accompanying drawings :Figures 1 and 2 are rear elevations of twoforms of Specification of Letters Patent.

Serial No. 486,233.

escutcheon plates embodying my invention. Fig. 3 represents a verticallongitudinal section of Fig. 1. Figs. 4E and 5 represent transversesections of Figs. 1 and 2 respec tively.

Similar reference characters indicate the same or similar parts in allof the views.

The escutcheon plate 10 is provided with suitable holes 11 for thescrews which attach the same to the door; said plate being ofcomparatively thin sheet metal, the edges of which are flanged asindicated in Fig. 3 to cause the main body of the plate to stand outfrom the wood.

The rose center or thimble 12 is provided with a circular flange snuglyfitting a hole in the plate 10 and spun at its edge to be firmly engagedtherein. At each side of the said hole the metal of the plate is formedwith ears for a purpose which will be presently described.

The combination support comprises a substantially rectangular plate 13having a marginal flange 14 the edge of which is substantially flushwith the edge of the escutcheon plate 10, said supporting plate 13having a hole 15 near one ,end which is somewhat larger than theconcentric hole in the escutcheon plate, slots 16 being formed at thesides of the hole 15. At: each side of the hole in the plate 10, themetal of said plate is formed with ears 17 for a purpose presentlydescribed. The other end of the supporting plate extends adjacent to theupper screw holes 11, and consequently the single iilate 18 supports thepressure of the knob rose and also of the upper attaching screws, andsupports the intermediate portion of the escutcheon plate against beingbent inward.

When the parts are assembled, the cars 17 are passed through the slots16 of the supporting plate and turned outward and clenched so as tofirmly secure the supporting plate against possibility of working looseor rattling. Portions of the flange of the thimble 12 are forced intothe spaces left by the bending up of the cars 17, as shown at 18 inFigs. 1 and 4E. Consequently the thimble also is locked againstpossibility of working loose and rattling.

Having now described my invent-ion what I claim is An escutcheon platehaving a hollow back and provided with a supporting plate, said plateshaving holes for the knob spindle the supporting plate having slots orrecesses, and the escutcheon plate having ears fitting said recesses andclenched therein, said supporting plate extending adjacent the upperscrew holes, and a thinible having a flange portions of which are forcedinto the recesses left by the ears of the escutcheon plate.

In testimony whereof I aflix my signature in presence of two witnesses.V
